Flexible Ducting: Polyflex
Flexible Ducting: Polyflex
The Polyflex core is a fully flexible metalized polyester duct consisting of 3 layers of 12 micron metalized polyester giving it a total thickness of 39 micron. A high carbon spring steel wire is encapsulated in these layers to give the flexible its body. It is a cheaper option to Aluflex ducts.
INSULATION
The Polyfex core is wrapped in 200 gram/m2 polyester fiber insulation which is held in place with a metalized polyester jacket. The metalized jacket also gives it an extra vapour barrier.
JACKET
The metalized polyester jacket is constructed with 2 layers metalized polyester.
APPLICATION
The aluflex flexible ducts are used in ventilation, air conditioning, and air handling systems where high mechanical strength, temperature and fire resistance is required.
TECHNICAL DETAILS
- Temperature range: -30° C to +100° C
- Air velocity:Up to 30m/s
Note: At these velocities sound through the flex could be generated. Recommended
velocity is 4m/s. - Operating Pressure: Max 2000Pa
- Bent radius: 1.5D (1.5 times the diameter)
- Diameter range: 102mm to 559mm
- Fire Safety:Metalized polyester ducts has not been fire rated.
- Lenghts: Standard lengths are 10 meters, other lengths are available on request.
- Packaging: The Polyflex plain is shrunk down from 10m to 30cm and the Polyflex insulated is shrunk down to 100cm and then placed in a colour coded plastic bag.
